'All the contributions are detailed, authoritative and clearly written, providing a thorough, critical picture of, as appropriate, current theory on the evolution of animal contests or the current status of relevant empirical research in particular kinds of animal. Taken as a whole, the editors have achieved their aim of providing an across-the-board perspective on the evolution of contest behaviour in animals that links a very extensive body of theory to a growing body of relevant empirical data.' Felicity Huntingford, Animal Behaviour
